On my 4cyl, I've only got to worry about the discs in the front. I'm not even going to look at the drum brakes in the back. Don't see why they would be shot if the front were fine before the disc warpage.

I'm still not clear about the clamp on the piston part. I saw the picture in the haynes manual, but you know how those things are. Never can tell what the fudge you're looking at in those pics!

I guess I will either bite the bullet and figure it out myself, or take it somewhere and hope they will install my parts and not cheat me.
